Abstract
Official abstract text for this publication.
Framing techniques for an improved radio link protocol used in a wireless communication system, such as EV-DO. In one embodiment scheduling of the generation of repair symbols encoded to be transmitted along with source data is described. In another embodiment acknowledgment messages from a receiver are used to control the trailing edge of the protection window offered by the repair symbols. In another embodiment, non-acknowledgment messages from a receiver are used to control the generation of extra repair symbols. In another embodiment, a length field is used to avoid transmission of padding bytes over the air. In yet another embodiment, a symbol auxiliary field is appended to source symbols to indicate the padding bytes needed for symbol aligning thus avoiding the transmission of padding bytes over the air.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, in a transmitter, of framing an upper layer packet Service Data Unit (ULP SDU), comprising: adding ( 1108 ) a Symbol Auxilliary Field (SAF) ( 862 ) to at least one source symbol ( 858 ) to indicate the boundaries of the ULP SDU and the length of potential padding needed to symbol align the ULP SDU; and encapsulating ( 1116 ) a portion of the ULP SDU along with at least one RS to form a PAL PDU, where the RS is generated by encoding ( 1110 ) at le…
